THOMAS E. STEVENS, OF GLENS FALLS, NEW YORK.

GRANITE currnve Ann McLnnve GAGE.

Application filed March 15, 1916.

To all whom it may concern Be it known that I, THOMAS E. STEVENS, a citizen of the United States, residing at Glens Falls, in the county of WVarren and State of New York, have invented certain new and useful Improvements in Granite Cutting and Molding Gages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in molding gages and it relates more particularly to that class of gages which are designed for the use of molders and stone workers.

The invention has for its object the provision of a simple, inexpensive and practical tool of this description by the use of which any desired curve, used in molding or in the form of the stone operated upon, can be quickly and accurately determined.

To this end and to such others as the invention may pertain, the same consists in the novel construction of the tool and in the peculiar arrangement, combination and adaptation of parts, all as will be more fully hereinafter described, shown in the accon'ipanying drawings and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this specification and in which Figure 1 is a plan view of the tool complete, the position of the straight edge attachment, when used, being indicated in dotted lines. Fig. 2 is a plan view of the straight edge attachment.

Reference now beinghad to the details of the drawings by numeral, 1 represents a strip of metal provided along one of its edges with a scale 2.

3 is a detachable member, the body portion of which is a compound curve, one edge of said member being provided with a right angled extension l provided with holes 5 to receive a pivot used in connecting the member to the strip 1.

(5 is a keeper having one of its ends secured to the face of the member 1 by a pivot or bolt 7, the opposite end of said Specification of Letters Patent. Pat nt-ed Sept, 19, 1916.

keeper 6 being curved slightly outwardly to permit the insertion of the member 3 be- Igween the keeper and the face of the mem- 8 is a metallic strip, the body portion of which is provided with an elongated recess 9 and its opposite end, which is preferably narrow as shown at 10, is secured to the member 3 at a point adjacent to its upper end by a pivot 11. The said member 8 is provided along one of its edges with a scale 12 and is secured to the strip 1 by a pivot 13 within the strip.

let is a metallic strip in the form of a straight edge, having one of its ends beveled or inclined as shown at 15, said straight edge being provided at one of its ends with a pivot opening 16 and at a point adjacent to its longitudinal center with a like opening 17.

The usefulness and operation of the invention will be at once readily understood. It will be seen that, when the compound curve arm 3 is pivotally attached to the face of the member 1 and its position with reference to the scale 2 is adjusted by loosening the screw 13 and forcing the upper end of the curved member to the desired position where it is secured by again tightening the pivot or bolt 13, a tool is provided which will serve the use of the operator in accurately determining curves designed to be produced upon the stone operated upon. It will also be seen that the position of the curved edges of the member 3 with reference to the scale upon the body portion or member 1 of the device can be readily adjusted by loosening the bolt or pivot 13 and moving the free end of the member in either direction, in which position it can be locked by the tightening of the bolt or pivot 13.

hen the exigencies occasion as indicated by the nature of the work to which the tool is to be applied requires the application of a straight edge rather than a construction involving curved lines, the straight edge member 14 is employed in place of the compound curved member 3. It will be noted that these members are readily interchanged.

YVhat I claim to be new is 1. A bar having a scale upon the face thereof, a keeper secured to the bar at one end and having a pivotal screw at its other end, a set screw secured to said bar and a slotted strip engaged by said set screw and having a scale upon its face, a bar adjustably held at one end to the pivot upon said ted strip and its other end having a lateral. keeper and its other end pivotally connectextension which, having a plurality of pered to the end of said slotted strip. forations therein, is adapted to be connected 2.
